Hypericum plant named ‘Allmadne’

ABSTRACT

A new and distinct cultivar of  Hypericum  plant named ‘Allmadne’, characterized by its broadly upright plant habit; moderately vigorous growth habit; dark green-colored leaves that are initially greyed red to greyed purple when developing; freely flowering habit and high fruit density; glossy greyed purple to black-colored fruits; and suitability as a garden or container plant.

Botanical designation: Hypericum hybrida.

Cultivar denomination: ‘ALLMADNE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hypericum plant, botanically known as Hypericum hybrida, typically grown as garden or container plant and hereinafter referred to by the name ‘Allmadne’.

The new Hypericum plant is a product of a planned breeding program conducted by the Inventor in Cuijk, The Netherlands. The objective of the breeding program is to create new Hypericum plants with numerous attractive glossy fruits.

The new Hypericum plant originated from an open-pollination in September, 2011 in Cuijk, The Netherlands of a proprietary selection of Hypericum hybrida identified as code number 11-37-2, not patented, as the female, or seed parent with an unknown selection of Hypericum hybrida as the male, or pollen, parent. The new Hypericum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled outdoor nursery environment in Cuijk, The Netherlands in October, 2012.

Asexual reproduction of the new Hypericum plant by vegetative cuttings in a controlled outdoor nursery environment in Cuijk, The Netherlands since October, 2012 has shown that the unique features of this new Hypericum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Hypericum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Allmadne’. These characteristics in combination distinguish ‘Allmadne’ as a new and distinct Hypericum plant:

-   -   1. Broadly upright plant habit.     -   2. Moderately vigorous growth habit.     -   3. Dark green-colored leaves that are initially greyed red to         greyed purple when developing.     -   4. Freely flowering habit and high fruit density.     -   5. Glossy greyed purple to black-colored fruits.     -   6. Suitable as a garden or container plant.

Plants of the new Hypericum differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Hypericum and the female parent selection         differ in developing leaf color as developing leaves of the         female parent selection are green in color.     -   2. Plants of the new Hypericum and the female parent selection         differ in fruit color as fruits of the female parent selection         are red in color.     -   3. Fruits of plants of the new Hypericum are more rounded in         shape than fruits of the female parent selection.

Plants of the new Hypericum can be compared to plants of the Hypericum hybrida ‘Alldiablo’, not patented. In side-by-side comparisons conducted in Cuijk, The Netherlands, plants of the new Hypericum differ primarily from plants of ‘Alldiablo’ in the following characteristics:

-   -   1. Plants of the new Hypericum and ‘Alldiablo’ differ in fruit         color as fruits of ‘Alldiablo’ are light pink in color.     -   2. Fruits of plants of the new Hypericum are more rounded in         shape than fruits of ‘Alldiablo’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown in September in 17-cm containers in an outdoor nursery in Hazerswoude-Dorp, The Netherlands and under cultural practices typical of commercial Hypericum production. During the production of the plants, day temperatures ranged from 16° C. to 30° C. and night temperatures ranged from 8° C. to 20° C. Plants were seven months old when the photographs and description were taken.
